Title:
  Deletion of the subnet is succeeding even when it's attached to a pool

Status in OpenStack Neutron (virtual network service):
  Expired

Bug description:
  Openstack: ICEHOUSE

  Description:

  UI page for Project ->Network->Load Balancers is not displayed.

  
  Steps:
  ========>
  1. Created a provider offering (type: LoadBalancer, driver: LB)

  2. Created a network, and subnet.

  3. Created a pool with subnet created above.

  4. Deleted the subnet without deleting the pool assoicated.

  5. Now the UI page for Project ->Network->Load Balancers is not
  displayed and thrown standard error page "something went wrong".

  
  Observed that subnet id is still attached as a part of the pool.
